On White-box Cryptography and Obfuscation
CoRR, 2008 We study the relationship between obfuscation and white-box cryptography. We capture the requirements of any white-box primitive using a \emph{White-Box Property (WBP)} and give some negative/positive results. Loosely speaking, the WBP is defined for some scheme and a security notion (we call the pair a \emph{specification}), and implies that w.r.t ...

Cryptanalysis of ARX-based White-box Implementations
Transactions on Cryptographic Hardware and Embedded Systems, 2023 At CRYPTO’22, Ranea, Vandersmissen, and Preneel proposed a new way to design white-box implementations of ARX-based ciphers using so-called implicit functions and quadratic-affine encodings. They suggest the Speck block-cipher as an example target.

White-Box Cryptography and an AES Implementation [PDF]
, 2003 Conventional software implementations of cryptographic algorithms are totally insecure where a hostile user may control the execution environment, or where co-located with malicious software. Yet current trends point to increasing usage in environments so threatened.

Towards Security Notions for White-Box Cryptography [PDF]
, 2009 While code obfuscation attempts to hide certain characteristics of a program independently of an application, white-box cryptography (WBC) specifically focuses on software implementations of cryptographic primitives in an application. The aim of WBC is to resist attacks from an adversary having access to some `executable' code with an embedded secret ...

Hardware Implementation of the GPS authentication [PDF]
, 2012 In this paper, we explore new area/throughput trade- offs for the Girault, Poupard and Stern authentication protocol (GPS). This authentication protocol was selected in the NESSIE competition and is even part of the standard ISO/IEC 9798. The originality

On Recovering Affine Encodings in White-Box Implementations
Transactions on Cryptographic Hardware and Embedded Systems, 2018 Ever since the first candidate white-box implementations by Chow et al. in 2002, producing a secure white-box implementation of AES has remained an enduring challenge.

Survey and Benchmark of Block Ciphers for Wireless Sensor Networks [PDF]
, 2006 Cryptographic algorithms play an important role in the security architecture of wireless sensor networks (WSNs). Choosing the most storage- and energy-efficient block cipher is essential, due to the facts that these networks are meant to operate without ...
